Missing 'Add New Version' Button in App Management UI

I am unable to see the Add New Version button in the Custom App Management UI for App ID: 261820, which prevents me from uploading new app versions.

Steps Tried:

  • Refreshed the page.
  • Cleared browser cache and cookies.
  • Tried accessing on different browsers.

Attached is a screenshot of the current UI for reference.

Please help resolve this issue. Let me know if additional details are required.
